HEMOSTATIC FORCEPS.

SPECIFICATION forming part of I Letters Patent No. 724,034, dated March31, 1903. Application filed September 10,1 1902." Serial No. 122,900.(No model.)

To all whom t may concern:

Beit known that I, WILLIAM LEGO NUT- TALL, a citizen of the UnitedStates, residing at Newcastle, in the county of Henry and State ofKentucky, have invented a new and useful Hemostatic Forceps, of whichthe following is a specification.

The invention relates to certain improve- Inents in forceps of thatclass employed for grasping the end of asevered artery, and has for itsprincipal object to provide an improved construction of forceps wherebythe ligature may be readily tied around the end of the artery at a pointcloseto the jaws of the forceps without danger of including the point ofthe instrument in the knotted loop.

A still further object of the invention is to so construct the forcepsas to provide for the formationV of the rst knot in the ligature and forsecurely holding the knotted loop on the forceps prior to closing theloop around the end of the artery.

With these and other objects in view the invention consists in the novelconstruction and arrangement of parts hereinafter described, illustratedin the accompanying drawings,and particularly pointed out in theappended claims, it being understood that various changes in the form,proportions, size, and minor details of the structure may be madewithout departing from the spirit or sacricing any of the advantages ofthe invention.

In the accompanying drawings, Figure l is a perspective view of a pairof hemostatic forceps constructed in accordance with the invention. Fig.2 is a side view of the same, showing the manner in which the first knotmay be formed in the ligature and held in readiness for application tothe artery. Fig. 3 is a view similar to Fig. 2, showing the manner inwhich the knotted loop is forced from the beak of the forceps to theartery.

Similar numerals of reference are employed to indicate correspondingparts throughout the several figures of the drawings.

The two jaws 1 and 2 ot' the forceps are of similar construction,pivotally connected at 3, and provided with any suitable form of handlefor convenience in closing the jaws of the forceps on the end of theartery. The artery-engaging surfaces are preferably serrated in theusual manner, as indicated at 4,

in order that they may freely engage with the artery, and at a point tothe rear of each of the serrated surfaces both jaws are recessed, asindicated at 5, invorder to weaken the jaws and permit the heel or rearend of each jaw to spring down when pressure is applied at the points ofthe jaws. The recessing further reduces the weight of theinstrument andpermits the better engagement of the jaws with the artery.

Thebeak of the forceps is preferably some'- what shorter than usual andmuch thicke'r in order to form a rounded or inclined end, with which theknotted securing-loop engages, and when tension is applied to the knotthe looped ligature will be forced over the end of the beak, slippingoff the instrument and securing the artery without risk of including thepoint of the instrument in the loop. On the outer surface of each jaw'isaforwardly-extending beard 6, so arranged as to permit of the formationof a knotted loop around theforceps in the manner shown in Fig. 2 andpermitting of the tightening of the loop to an extent sufiicient toprevent the ligature from becoming tangled or twisted upon itself whiletaking the first knot, which is the most difficult in operations of thischaracter.

In using the forceps the artery is engaged and clamped between the jawsin the usual manner, any suitable means being employed,

and the ends of the jaws closed on the artery.

The ligature is then looped around the lower beard and the upper portionof the forceps, as indicated in Fig. 2, the knot being drawnsufficiently tight to prevent twisting of the ligature. The knotted loopis then lifted over the upper beard and tension is applied to force theloop down over the inclined beak into engagement with the artery, thebeak being sufficiently large and inclined or rounded in such manner asto avoid the possibility of including the point of theinstrument in theknotted loop. A

Having thus described myinvention, what I claim isl. A pair ofhemostatic forcepsy comprising a pair of pivotally-connected jaws eachhaving a rounded and inclined face to permit of the forcing of a knottedligature from the forceps into engagement with an artery, andoppositely-disposed loop-engaging beards form IOO with a rounded beakand with forwardly-tafurther provided with a member having a reL cessedfront face and a curved rear face, the latter being disposed at a pointin advance of the reduced portion of the jaw adjacent to I the pivot.

ing a part of said jaws, each beard having a recessed front face and acurved rear face, the latter being disposed at a point in advance of thereduced portion of the jaws adjacent to the pivot.

2. A pair of hemostatic forceps, comprising a pair ofpivotally-connected jaws having gripping-surfaces, each jaw beingprovided my own I have hereto aiiixed my signature in the presence oftwo Witnesses.
